Emflon® PFR Membrane Filter Cartridges

High Strength, Long Life Sterilizing Filters for Air and Gas

Emflon® PFR filters have been developed from the successful Emflon filter range launched in 1981 and widely used as air and gas sterilizing filters in the pharmaceutical and biotechnology industries. The double layer PTFE membrane is inherently hydrophobic, chemically inert and designed specifically for removal of contaminating bacteria and viruses. Emflon PFR filters meet the ever increasing demand for air filters with greater strength, longer life and the ability to withstand the rigours of in-situ steaming in the forward or reverse direction.

Superior Performance

Emflon PFR filters provide high assurance of filter integrity and long life, even during continuous use in hot air up to 60°C, in vent applications up to 80°C and during repeated steaming. The filters can withstand up to 1 bar (14.5 psi) differential pressure (forward direction) under steam sterilization conditions (125°C). This is combined with high flow rates and excellent dewetting characteristics resulting in very economical filtration through the use of smaller installations and reduced energy costs. In addition, the filters can be tested in-situ by the Forward Flow integrity test or by a Water Intrusion test. Both tests are correlated to liquid bacterial challenge - the ‘worst case’ challenge.

Scientific Validation

Emflon PFR filters have been extensively and scientifically validated using the most advanced methods and the most sensitive equipment available. They have an absolute removal rating of 0.2 µm in liquids and 0.003µm in gases and have been validated by:
